center of mass - JaneliaSciComp/JRCLUST GitHub Wiki

Center of mass is calculated for each spike or cluster using the following formula:

x_cm = sum(sx_k * a_k^2, k=1..n) / sum(a_k^2, k=1..n)

• sx_k: x coordinate value of site k
• a_k: first principal component value of spike waveform at site k
• k: site index
• sum(b, b=1..10): sum of b from 1 to 10
